This is not strictly an API change as GdkDrawable is typedeffed to
GdkWindow, but it changes the header, so I'm marking it as such.
gdk_cairo_create() can only be used with windows these days, so it makes
sense to pass a window. With that, we can alseo remove the
set_cairo_clip() vfunc from GdkDrawable and implement it inside
gdkwindow.c.
You should not ever ever ever call cairo_reset_clip(). If you do, your
code is broken and you deserve everything you get.
And we should definitely not support this insanity.
This fix has evolved in the staging branch since all column members are
on a private structure, but since it causes warnings when closing the
windows of the testcellarea test (because the combo-boxes use a treeviewcolumn)
I thought it nice for now to just manually include the fix.
The fix is just proper bookkeeping of delegate objects at dispose() time.
It's a better test case if the scaffolding only displays the rows from top
to bottom and doesnt line up the cells from left to right (because it shows
that height-for-width still works with vertically oriented areas).
- When we reach a cell that is out of the render area, break out
of the loop (for columns user resized too small)
- CLAMP the size of the last renderer to fit into the area
(so that renderers get a chance to ellipsize when rendered
with a space less than allocation, same reason as above).
- Hand out remaining space in the render area to the last cell,
this is for shallow rows in the expand column which may recieve
more than the allocated width.
If the area has no activatable cells and has focus when
focus should be cycled, immediately focus out of the area
(because focus in that case is given to the entire area).
Thomas Wood pointed out that the original MxGtkLightSwitch widget upon
which I based the behaviour of GtkSwitch was not written by him; the

My apologies to all of them.
